Instant Reload not reloading on Mac

Hi there,
I try desperately to make Instant Reload to fire up in my workflow.
I did not succeded. Do you have a clue what the Problem could be ?

  • I’m on macOS Monterey 12.3.1
  • Using Safari
  • On custom themes
  • Editing with Panic’s Nova
  • Compiling scss with CodeKit

Thanks a lot for your help.

best regards

Julien
